Title: Improvements in or relating to push-broaching machines
IPC: B23D37/04
Filed: 1936-08-13
Abstract: 479,870. Broaching- machines. WEATHERLEY, H. E., and WEATHERLEY & CO., Ltd.. H. E. Aug. 13, 1936, No. 22347. [Class 83 (iii)] A push-broaching machine has the broach 1 supported at both ends during the cutting stroke. The upper end of the broach is locked during operation to a ram head 2 actuated by a hydraulic cylinder 3 having a fluid supply controlled by a, lever 24. The locking plunger 5 is actuated through a lever 7 by a push rod 8 controlled by stops on a rod 9. The lower holder 11 comprising a cup into which the lower end of the broach fits, is moved along guides 12 by rack and pinion gearing 13 operated from a driving shaft (not shown) through a clutch 15 which is controlled by the operator by means of a lever 16. In its uppermost position beneath the work table 4, the holder is supported by a spring pawl 29, and in the lowest position the holder engages an adjustable stop 22. The holder can also be connected to the ram head by means of a pawl 18 engageable with a slot in a rod 17 secured to the head, the pawl being disengageable by means of a cam 19. At the beginning of a cycle the head 2 with broach locked therein is in its uppermost position and the holder is also locked in raised position by the pawl 29. The work piece is positioned and the ram head brought down by operation of lever 24 until the broach engages the socket in the holder. At the same time the head and the holder are locked together by pawl 18 and pawl 29 disengaged. The ram head now completes its stroke through the work and towards the end of the stroke the cam stop 10 on the control rod engages rod 8 to free the broach from'the head and the holder 11 is disengaged from the head by the cam 19. The rod 9 is now moved downwardly by the engagement of a part of the head with the cam 10 and thus operates a valve to reverse the head which makes part of its return stroke until the push rod 8, which owing to the release of the broach now protrudes farther from the broach axis, engages a member 21 to cut off fluid supply to the ram cylinder. The holder 11 meanwhile moves downwards by gravity against braking means until it engages with the stop 22, the broach then being in a position which permits removal of the work. After removing the work the holder is raised by the rack and pinion mechanism until the broach engages and is locked in the ram head and pawl 18 locks the holder to the head. Locking of the broach removes the rod 8 from the stop 21 and the rod 9 descends to operate a valve to supply fluid to continue the upward stroke of the ram. The holder is carried upwards also until it is disengaged from the rod 18 and remains supported in its upper position by pawl 29. The ram continues upwards until a stop 23 is engaged to shift the control rod and stop the ram with all the parts positioned for a fresh cycle. The machine may also be applied to surface broaching.

Abstract: 424,267. Moulds for concrete &c. blocks &c. REINFORCED CONCRETE BUILDINGS, Ltd., and TEMPLE, J. E., 2, Robert Street, Adelphi, London. Aug. 15, 1933, No. 22780. [Class 87 (ii)] In moulding building-blocks or the like from cement or concrete in a semi - dry condition, four separate, but loosely interconnected metallic liners a, c are inserted in a mould, the concrete is introduced and lightly tamped to consolidate the mass and bring the liners into co-operation, the liners and contained material are removed and the material allowed to set. The liners have sufficient strength and rigidity to preserve the shape of the casting while plastic and the pressure of the plastic mass prevents relative displacement of the liners which can readily be removed when the mass is set. One pair a of liners may have corrugations b so as to bind into the casting material and the other pair c may have end flanges c<1> which engage the ends of the pair a and hold the casting together while hardening. They may be used with a mould having four rigid metal sides and open at top or bottom or one having movable sides. Specification 292,425, [Class 87 (ii)], is referred to. According to the Provisional Specification, they may be used with the mould described in Specification 424,269.

Patent GB-978818-A (GB)
Title: Improvements in or relating to potato products
IPC: A23L19/18
Filed: 1963-06-10
Abstract: A potato product is produced by reducing the particle size of raw potatoes to form a mixture of finely divided solids and liquid, increasing the viscosity of the mixture, forming the mixture into shaped bodies and subsequently cooking the shaped bodies.  A crisp, friable potato chip containing up to 10% by weight of moisture and up to 50% of fat, may be obtained by reducing the particle size of raw potatoes to form a pulp (preferably of moisture content as low as about 55%), heating the pulp to a temperature of from about 65 DEG C. to 100 DEG C. to gelatinize at least 80% by weight of the starch, cooling to a temperature within the range of from about -1 DEG C. to 38 DEG C, forming the pulp into chips, dusting the chips with flour, drying to bring their solids content up to from 50 to 90% by weight, and subsequently deep frying the dried chips in frying oil (specified).  The viscosity of the finely-divided potato solids and liquid may alternatively by increased by separating 40-80% by weight of the solids and liquid, and forming an admixture of the finely divided solids with up to 10% of their weight of a gelling agent such as methyl cellulose, carboxymethyl cellulose, pregelatinized wheat starch, waxy maize starch, agar or mixtures of these.  Proteins may be recovered from the separated liquid as by heat coagulation and returned to the solids phase.  Before any separated liquid is returned to the solids phase, its content of reducing sugars and amino acids is removed by fermentation or enzymatic oxidation and ion exchange, respectively.  Spices, seasonings and flavourings such as sugars, salt, gluten, hydrogenated vegetable protein, soy flour, monosodium glutamate, lecithin, fats and barbecue seasoning may be included in the mixture.  The potato pulp may be shaped by extrusion or by rapidly cooling it to about -2 DEG C. and slicing the mass into pieces of the desired shape and size.  According to an example, discs of raw potato of about 6.4 mm. thickness were treated with aqueous sodium bisulphite solution and put through a high speed cutting mill to produce a pulp having a viscosity of 7 x 104 c.p.s.  This pulp was heated for 5 minutes in a scraped-surface heat exchanger to a temperature of 93 DEG C. to gel at least 80% of the starch in the pulp.  After coling, the pulp of viscosity of 2 x 106 c.p.s. was extruded through an orifice of varying width into elliptical-shaped chips.  The chips were heated in a hot air oven and then fried by submerging them for 5 seconds in fat at 193 DEG C.

An adaptor for a spinning reel 10, having a central shaft 23, enables the line spool to be changed rapidly. The adaptor consists of a flanged portion 38 upon which is mounted a boss 37. The adaptor is attached to the central shaft by flats 46 locking into a shaped hole in plate 42. The line spool slides over dragnut 40 onto the boss 37 and is retained against axial movement by grips 57 made of resilient material. The dragnut 40 compresses a washer 41 held in place by plate 42, in this way a variable drag between the driving means and the spool may be produced. Axial rotation of the spool relative to the adaptor is prevented by 1ug 50 engaging slot 51 (in an alternative embodiment projections in the adaptor flange fit into holes on the spool), by the grip 57, and by key 58 on the spool engaging keyway 59 on the adaptor boss. A spool specially for use with this adaptor is also described. A special sleeve may be fitted on the adaptor boss to enable spools with different internal diameters to be used. A click mechanism is also provided, consisting of a ratchet bearing on wire.
